* Note: Difference from Acid Solutes. Purity of the
Diatomaceous Earth ( Fossil Shell Flour) was confirmed by MALDI mass
spectometry, indicating that the material is virtually free from any other
form of contamination. MALDI is a technique in which the matrix is used to
assist ionization of molecules on the surface of the material,
caused by a blast from a UV Laser. This analysis confirms purity and
suggests that even the above listed trace elements are not readily ionized
and volatilized from the surface.
